AXLE-BOX.

SPECIFICATION forming part of Letters Patent No. 554,186, dated February4, 1896.

Application filed September 5, 1895. Serial No. 561,494. (No model.)

To all whom it may concern:

Be it known that I, HENRY A. HYLE, a citizen of the United States ofAmerica, residing at Redwood, in the county of Jefferson and State ofNew York, have invented certain new and useful Improvements inAxle-Boxes and I do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings, and to letters ofreference marked thereon, which form a part of this specification.

This invention consists in providing an axle-box with spiral flangeshaving knifeedges, two sets of flanges being provided so that they willengage different parts of the hub.

In the accompanying drawings, forming part of this specification, Figure1 is a side elevation, and Figs. 2 and 3 are sectional views on thelines 2 2 and 3 3 of Fig. 1.

A designates the axle-box, the general configuration of which is of theordinary type.

My invention consists in applying to the forward part a of the axle-boxA a series of curved or spiral flanges B, which are provided withknife-edges, and in applying to the rear end a of the axle-box aseriesof curved flanges O, which are positioned so as to be out of line withthe flanges B.

In manufacturing my improved axle-box the flanges B and O are formedintegral with the box, and the flanges B commence at a point a shortdistance from the forward end of the axle-box and terminate at theshoulder a WVhile the flanges O are located at an equal distance apartas the flanges B, they are out of line with the latter. Both sets offlanges are provided with knife-edges and the forward ends aresharpened, as shown.

An axle-box constructed as hereinbefore described may be driven into thehub without the use of any special tools, and when driven into positionwill be held securely against rotation in the hub. When the axle-box isbeing driven into the hub, the curved flanges will cause the same toturn. Should the spindle at any time become jammed in the axlebox, thetendency of the tightening will be to draw said axle-box farther intothe hub,which will be resisted by the shoulders. By commencing theflanges a short distance from the forward end of the axle-box saidforward end serves as a guide for inserting the box into the hub. Theknife-edges of the flanges will cut their way into the wooden hub whenthe axle-box is being driven therein, and will also out through anyknots that may be in the huh.

I am aware that prior to my invention it has been proposed to provide anaxle-box or bushing with continuous flanges or screwthreads; but thepitch of the threads is such that it requires a special tool to insertthe box into the hub. I am also aware that it is not new to provide theinner portion of the hub with straight flanges. not claim suchconstruction as my invention; but

What I do claim as new, and desire to secure by Letters Patent, is-- 1.An axle-box or bushing for hubs having a reduced forward portionprovided with longitudinally-curved flanges B, and an enlarged rearportion with longitudinally inclined flanges O, the flanges B and Chaving sharpened front edges and being positioned out of line with eachother, substantially as shown.

2. An axle-box or bushing for hubs having a plurality oflongitudinally-curved flanges B with knife-edges and sharpened forwardends, said flanges extending from a point near the front end of theaxle-box to the shoulder thereof, and flanges O on the enlarged rearportion of the axle-box having knife-edges and sharpened forward ends,the flanges 0 being inclined with respect to the longitudinal center ofthe axle-box and positioned on a line between the rear ends of theflanges B substantially as shown and for the purpose set forth.

In testimony whereof I-affix my signature in presence of two witnesses.
